Mark anthony

Spark notes
Antony -  A friend of Caesar. Antony claims allegiance to Brutus and the conspirators after Caesar’s death in order to save his own life. Later, however, when speaking a funeral oration over Caesar’s body, he spectacularly persuades the audience to withdraw its support of Brutus and instead condemn him as a traitor. With tears on his cheeks and Caesar’s will in his hand, Antony engages masterful rhetoric to stir the crowd to revolt against the conspirators. Antony’s desire to exclude Lepidus from the power that Antony and Octavius intend to share hints at his own ambitious nature.

In the interrogation scenes we could use the fact that mark Anthony turned the people of Rome against Brutus. We could use it in a way like "You obviously wanted to make the people of Rome hate Brutus so the blame is shifted away from you"
